again i wouldn't judge dude at all if he missed the super bowl for this but there's really not much he can do either way. as someone who has given birth (albeit through c-section) i can honestly say i'd prefer he not miss the super bowl for that my father never saw any 4 of us get born and he says has no regrets lol he's squeamish so even when he was allowed in when my younger brother & sister was born he declined for me and my older sisters birth he wasn't allowed.
on the other hand though if the birth is on his mind it might effect his performance so he should just do what's best for him.
